SFCxxB16GExD SFP Dual Fibre CWDM ITU CWDM / 16dB / Gigabit Ethernet For your product safety, please read the following information carefully before any manipulation of the transceiver: ESD This transceiver is specified as ESD threshold 1kV for SFI pins and 2kV for all others electrical input pins, tested per MIL-STD-883G, Method 3015.4 /JESD22-A114-A (HBM). However, normal ESD precautions are still required during the handling of this module. LASER SAFETY This is a Class1 Laser Product according to IEC 60825-1:2007. This product complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice No. 50, dated (June 24, 2007). The optical ports of the module need to be terminated with an optical connector or with a dust plug in order to avoid contamination. 1. Overview SFCxxB16GExD is a high performance transceiver module for Gigabit Ethernet data links over a single mode fibre pair. The power budget 1 is 16dB end of life (EOL).The transmitter is a CWDM DFB laser, the receiver is a PIN photodiode. This transceiver module is compliant with the Small Form-factor Pluggable (SFP) Multisource Agreement (MSA) and hot pluggable. Always contact Skylane Optics commercial agents for compatibility with different equipment platforms. 2. Features SFP Multi-Source Agreement compliant [INF-8074i] Hot pluggable SFP footprint Serial ID functionality supported according to [SFF-8074i] Class 1 laser safety standard IEC 60825 compliant Dual LC connector CWDM DFB transmitter (channels 27 to 45) PIN receiver Power budget >16dB Operating temperature range 0 C to 70 C or -20 C to 85 C Low power dissipation (<1W) Digital diagnostics monitoring (DDM) Figure 1.

9. Transmission Reach The actual transmission reach is depending on the CWDM channel used, due to the wavelength dependent attenuation in the fibre path. The table below shows the estimated transmission reach for CWDM channels 27 to 45. NB: Distances are purely indicative and only valid for G.652 fibre. Only the optical power budget is guaranteed. Additional optical insertion loss from CWDM filters, splices, optical connectors etc. is not included.
